How would you rate this event overall? - 83% (excellent and really good) If you attended either of the forward-looking sessions, did you find them relevant to the industry and something GENIVI should act on? Yes, I believe the Common Vehicle Interface Initiative is relevant and GENIVI should act on it - 75% Yes, I believe the Domain Consolidation topic is relevant and GENIVI should act on it - 42% Day 2&3 sessions rated Excellent to Good AASIG Workshops – 67% Cloud & Connected Services – 58% Cybersecurity – 50%

Showcase Demo Videos 42% were very interested 42% Somewhat interested 16% did not have time to watch the videos

Easy to access ? 83% said it was very easy

• Even surprisingly positive experience. Active discussion and questions from audience visible. In some sense, this worked even better than f2f sessions! • Thanks, It was the great session • The topics for the event was relevant.

Copyright © GENIVI Alliance 2020 6 6 Summit Debrief: We reached out through the noise and informed people about the on-going GENIVI work • Common Vehicle Interface Initiative • Panel-like discussion thanks to Bosch, McKinsey and Renault • Follow-up needs to be undertaken very soon with Microsoft, OEMs, other cloud providers • Readouts • Cybersecurity • Automated Testing • Workshops • AASIG Vehicle Data/VHAL , AASIG Audio HAL , Cloud & Connection Services • Very good preparation and leadership provided by GENIVI project team participants • Demos delivered by TietoEVRY, High-Mobility, Geotab and Samsung (and shown live) • Discussion topics identified and prepared, next milestone content identified • Very good participation of a few workshop attendees, many good questions, e.g. AASIG: MBtion, Microsoft, Huawei, GHS, KPIT, Alpine, P3 • Minutes (and slides) are available in the wiki (thanks to minutes taker), link: https://at.projects.genivi.org/wiki/x/QgJUAw 7 Vehicle Data APIs / VHAL Report

8 Android Automotive SIG ‐ Vehicle Data APIs - VHAL – External Data Server Concept

Design choices made by the group

cmp Google VHAL + External Data Server

Head Unit (on‐board) Application layer Defined by • VSS adoption (Vehicle Signal

Google «App» «App» WebSocket Manifest Specification) – will be introduced App 1 App n Genivi OEM / Tier1 in the CCS project report «trace» OSS Framework layer CarAPI

Java API • Coexistence of Google VHAL and

Authentication Car API Virtual ECU (same / different ECU) Data Server Service UnixDomainSocket Apollo GraphQL

Package Manager Car Service • Application authentication

HIDL • Interface with the « rest » of the HAL layer vehicle, e.g. via Some/IP

10 Android Automotive SIG ‐ Vehicle Data APIs - VHAL – Report • Team participants: BMW, Daimler, (Jaguar Land Rover), TietoEVRY, Bosch, EPAM • Topics discussed at the tech summit • Google Vehicle Properties Implementation based on GraphQL Service. • Permission groups specification. • Translation of permission groups. • JWT Token what will be included and how it will be done? And generation process? • Next steps towards the next milestone (mid-July) • Addition of permission model to GraphQL • GraphQL resolver update • Sync with CCS project for using the same vehicle data (database) • Technical readiness level assessment and discussion on how and when to reaching out to Google • VSS as an alternative or complement to Google Vehicle Properties • Access to vehicle data via GraphQL instead of Key Value pairs • Backlog update in-progress

12 Android Automotive SIG – Audio HAL – Report • Main thread of work - How to Control a Car Audio System with Android

Providing sources and sinks Controlling the complete System

Audio Audio Source Audio Sink Source Audio Audio Audio Sink Source SourceAudio Audio Source Source

sources streams / input stream raw streams raw streams input streams

Audio Audio Source Source Audio Sink Audio Audio Source Audio Sink Source Audio Audio Source Source

green and blue boxes can be partitions / virtual machines or different HW

• Both strategies have advantages and disadvantages • Relying on Android only does not fulfill some safety requirements • Considering Android as sources and sinks only does not take enough advantage of it • Therefore each topic has to be analyzed and assigned : inside or outside Android

13 Android Automotive SIG – Audio HAL Proof Of Concept - Getting Raw Streams

System Level Audio Manager OS Level Audio Manager Proxy

System Level Audio Manager

• Reference design from Google side by side to the GENIVI Proof Of Concept proposal • Android design relies on an External System (Mixer, Amplifier, Safety signals,…) • GENIVI Proof Of Concept tries to provide an concrete instantiation of the Audio Control Split

14 Android Automotive SIG – Audio HAL – Report

• Team participants: BMW, Mobis, TietoEVRY, EPAM, Bosch, Analog Devices

• Main thread of work - How to Control a Car Audio System with Android • proof-of-concept implementation in-progress - Getting raw streams out of Android • Demo was shown in the workshop • Source code repository https://github.com/GENIVI/android-external-audio-mixing • Topics discussed at the tech summit • Audio Manager integration (Android audio manager & GENIVI Audio Manager co-existence) • Proof-of-concept architecture & “prerequisites” : extracting raw streams, injecting input streams • Feature content definition for next milestone : • Utilization of actual hardware instead of Android emulator • Going through the list of prioritized topics for and refining the priorities with participants • Backlog update in progress

15 New project opportunities

• Broadcast radio and Android

• Location-based services and Android • How to plug alternate navigation engines
